Spain’s single national short-term rental registry was declared null by the Supreme Court in judgment 620/2026 of 21 May 2026. Owners are no longer obliged to obtain the national registry number or to file the annual rental declaration. Everything else that governs a Costa del Sol let — the Andalucían tourist registry, the municipal position, the community statutes — is unchanged.
Royal Decree 1312/2024 created the registry and it went live on 1 July 2025. For eleven months it was the headline obligation in every briefing on Spanish holiday letting: one number, one national database, one annual declaration. It is now void — and the practical position of an owner in Mijas or Marbella has moved much less than that headline suggests.
What falls and what survives
The table below separates the elements of Royal Decree 1312/2024 that were annulled by Supreme Court judgment 620/2026 of 21 May 2026 from those that remain in force after it. It describes the position at 1 August 2026 and covers only the national instrument — regional and municipal obligations were not before the court and are dealt with separately below.
| Element of Royal Decree 1312/2024 | Status after judgment 620/2026 (21 May 2026) | Practical effect for an owner |
|---|---|---|
| Obligation to obtain the single national registry number for each short-term rental unit | Falls — annulled | No longer required. An owner who never obtained one is not in default for that reason |
| Obligation to file the annual rental declaration to the national registry | Falls — annulled | No longer required |
| Pending disputes with property registries over the grant or refusal of a registry number | Falls away — may be dismissed as moot | The underlying obligation no longer exists, so the dispute may have nothing left to decide |
| Digital single window for data collection | Survives | Continues to operate; it rests on the state’s powers over economic coordination and national statistics |
| Obligation on booking platforms to transmit rental data | Survives | Letting activity booked through platforms continues to be reported to the state |
| Statistical reporting | Survives | Aggregate data on short-term letting continues to be collected and published |
The line between the two halves of that table is the whole of the judgment. The obligations placed on the owner fell. The machinery that observes the market did not. An owner who reads “the registry was struck down” as “nobody is watching” has drawn precisely the wrong inference from a ruling that left the surveillance apparatus intact and removed only the paperwork.
The reasoning: competence, not policy
The court did not rule that a national short-term rental registry is a bad idea. It ruled on who may create one.
The first ground was competence. The state lacked the competence to create a national registry that overlapped the tourism registries already maintained by the autonomous communities. Tourism is a regional competence in Spain, the regions had already built registries under it, and a parallel national instrument sitting on top of them was held to exceed what the state could do.
The second ground was the constitutional heading the decree relied on. Royal Decree 1312/2024 was founded on article 149.1.8 of the Constitution. The court held that this could not support it, because the decree neither regulated substantive rental law nor created a burden enforceable against third parties. It was, on that reading, an administrative registration requirement resting on a justification that did not fit it.
I set the reasoning out narrowly because it deserves to be read narrowly. A decision on competence tells you which authority may impose an obligation. It does not tell you that the obligation will not be imposed — only that it will be imposed by somebody else.
Where responsibility sits now
Verification of seasonal and tourist lets now sits with the autonomous communities, and the Housing Ministry has urged the regions to accelerate their own verification work in the wake of the judgment. For a property anywhere on this coast, that means the Junta de Andalucía and its Registro de Turismo de Andalucía.
This is not a soft landing. Andalucía’s programme did not pause while the Supreme Court deliberated. The figures below were reported by the Junta de Andalucía in June 2026 and describe activity across the region, not this coast alone.
| Enforcement measure, Andalucía | Reported figure | Period |
|---|---|---|
| Growth in registered tourist homes | 3.12%, down from 16.89% | 2025, against the preceding period |
| Registrations cancelled | More than 15,300 — roughly 10% of the region’s registered stock | Since January 2024 |
| Bed places removed by those cancellations | About 80,000 | Since January 2024 |
| Dwellings investigated for irregularities | More than 16,000 | Reported June 2026 |
| Public enquiries handled | More than 11,700 | Since August 2025 |
| Joint enforcement operation with the Policía Nacional | “Proyecto Titán”, against unlicensed operators | Reported June 2026 |
| Formal agreements with municipalities with heavy tourist-accommodation activity | 10 | Reported June 2026 |
Read the first row with the second. Growth in registered tourist homes in Andalucía fell from 16.89% to 3.12% in 2025 while more than 15,300 registrations were cancelled — roughly a tenth of the region’s registered stock, removing about 80,000 bed places. That is not a market cooling of its own accord. It is a register being pruned.
The honest conclusion is that the enforcement pressure has not gone away. It has changed address. The authority that lost a registry on 21 May 2026 had built it eleven months earlier and done comparatively little with it. The authority that gains sole responsibility had already cancelled 15,300 registrations and run a joint operation with the national police.
Three checks, in this order
First, verify your Andalucían registration. Confirm that the property is correctly entered in the Registro de Turismo de Andalucía, that the entry matches the dwelling as it actually exists, and that nothing in it has lapsed. With more than 16,000 dwellings investigated for irregularities, an entry that is stale or inaccurate is a live exposure rather than an administrative untidiness. This is now the licence that matters.
Second, verify the municipal position. The council decides whether new registrations are possible at all, and the regimes on this coast diverge sharply — Málaga city closed, Fuengirola restricted and pursuing cancellations, Mijas and Estepona open. We set out all eight municipalities in our guide to tourist rental licences on the Costa del Sol, municipality by municipality. The boundary matters more than the address: two apartments a few hundred metres apart in somewhere like La Cala de Mijas or on a municipal boundary can sit under different regimes entirely.
Third, verify the community statutes. This is the check owners skip and the one that is close to impossible to fix afterwards. Two resolutions of the DGSJFP concerning the Benalmádena No. 2 property registry — BOE-A-2026-1524, resolved 8 October 2025, and BOE-A-2026-3182, resolved 17 October 2025 — were both decided against the owner where the statutes prohibited commercial activity or tourist accommodation. An administrative tourism licence does not override the statutes. We deal with the point in full in our article on what community statutes can do to a tourist rental.
For a buyer rather than an existing owner, all three checks belong before exchange, alongside the rest of the due diligence set out in our guide to buying property on the Costa del Sol. Rental income assumptions that survive none of these checks are the most common flaw I see in a Costa del Sol investment case.
This is general information, not legal or tax advice. The position on any specific property should be confirmed with a Spanish lawyer or asesor fiscal before you act on it.
What is not yet clear
Two things are genuinely unresolved at 1 August 2026, and I would rather say so than fill the gap.
Whether the regions will legislate further is unknown. The Housing Ministry has urged them to accelerate verification, but urging is not legislating. Andalucía may extend its registry regime, tighten its verification rules, or simply continue the enforcement programme it already runs under existing powers. I have no verified draft to describe, and I am not going to characterise one from the direction of travel.
What happens to owners mid-dispute is also unsettled. Pending disputes with property registries over registry numbers may be dismissed as moot, which is the orderly outcome. How individual files are actually being closed, whether refusals already issued are formally withdrawn, and what happens to an owner who acted on a refusal, are questions I cannot answer from a verified source as of 1 August 2026. Anyone in that position should take specific advice rather than assume the file has quietly disappeared.
Common questions
Do I still need a national registry number?
No. The obligation to obtain the single national registry number under Royal Decree 1312/2024 was annulled by Supreme Court judgment 620/2026 of 21 May 2026. The annual rental declaration to the national registry went with it. Your regional and municipal obligations are entirely separate and are unaffected by the judgment.
Is my Andalucían tourist licence still valid?
Yes. The judgment concerned a national instrument only. Registration in the Registro de Turismo de Andalucía was never part of Royal Decree 1312/2024 and is untouched by the ruling. It is now the principal registration that governs a short-term let on the Costa del Sol, which makes verifying that your entry is current more important, not less.
Do the booking platforms still report my rentals?
Yes. The obligation on platforms to transmit rental data survived the judgment, along with the digital single window and statistical reporting, because those rest on the state’s powers over economic coordination and national statistics rather than on the annulled registry provisions. Bookings made through platforms continue to generate data the authorities receive.
Does this mean short-term letting is easier now?
No. One layer of national paperwork was removed while every substantive constraint stayed in place — the Andalucían registry, the municipal regime, the community statutes. Andalucía cancelled more than 15,300 registrations between January 2024 and June 2026 and investigated more than 16,000 dwellings. The pressure has changed address, not intensity.
My registry number application was refused or is still in dispute. What now?
The obligation the dispute concerned no longer exists, and pending disputes with property registries may be dismissed as moot. How individual cases are being closed in practice is not something I can confirm from a verified source at 1 August 2026. If you acted on a refusal — stopped letting, or restructured — take specific legal advice before assuming the position has reversed.
